helping each other. Join them; it only takes a minute: Sign up Error Code: 1005. Can't create table '…' (errno: 150) up vote 74 down vote favorite 30 I searched for a solution to this problem on internet and checked the SO questions but no solution worked for my case. I want to create a foreign key mysql errno: 121 from table sira_no to metal_kod. ALTER TABLE sira_no ADD CONSTRAINT METAL_KODU FOREIGN KEY(METAL_KODU) REFERENCES metal_kod(METAL_KODU) ON DELETE SET NULL ON UPDATE SET NULL ; This script returns: Error Code: 1005. Can't create table 'ebs.#sql-f48_1a3' (errno: 150) I tried adding index to the referenced table: CREATE INDEX METAL_KODU_INDEX ON metal_kod (METAL_KODU); I checked METAL_KODU on both tables (charset and collation). But couldn't find a solution to this problem. Does anyone have any idea? Thanks in advance. EDIT: Here is the metal_kod table: METAL_KODU varchar(4) NO PRI DURUM bit(1) NO METAL_ISMI varchar(30) NO AYAR_YOGUNLUK smallint(6) YES 100 mysql mysql-error-1005 share|improve this question edited Jan 27 '14 at 7:57 Melon 786617 asked Jan 26 '12 at 13:14 lamostreta 85122046 Can you show the schema for the metal_kod table ... which field in that table should the Foreign Key reference ? –ManseUK Jan 26 '12 at 13:28 add a comment| 9 Answers 9 active oldest votes up vote 199 down vote accepted Error Code: 1005 -- there is a wrong prima

This is the code that causes the error: CREATE TABLE season ( id smallint unsigned NOT NULL auto_increment, title varchar(25) NOT NULL, PRIMARY KEY (id) ); CREATE INDEX seasonId ON season(id); DROP TABLE IF EXISTS event; CREATE mysql error 1005 TABLE event ( id smallint unsigned NOT NULL auto_increment, title varchar(255) NOT NULL, season_id smallint NOT NULL, PRIMARY KEY (id), FOREIGN KEY (season_id) REFERENCES season(id) ON UPDATE RESTRICT ON DELETE RESTRICT ); So according to the error there is a problem with my foreign key declaration. However I had already run this code on the machine with no problems, and it ran perfectly on my Linux Machine as well (I'm currently working under Windows 7). Here is the output of SHOW ENGINE INNODB STATUS: ------------------------ LATEST FOREIGN KEY ERROR ------------------------ 120229 17:43:28 Error in foreign key constraint of table fcrcontent/event: FOREIGN KEY (season_id) REFERENCES season(id) ON UPDATE RESTRICT ON DELETE RESTRICT ): Cannot find an index in the referenced table where the referenced columns appear as the first columns, or column types in the table and the referenced table do not match for constraint. Note that the internal storage type of ENUM and SET changed in tables created with >= InnoDB-4.1.12, and such columns in old tables cannot be referenced by such columns in new tables. See http://dev.mysql.com/doc/refman/5.5/en/innodb-foreign-key-constraints.html for correct foreign key definition. I also tried running my script on a fresh database, but no go.

It has to do with trying to successfully set foreign keys in MySQL. ERROR 1005: Can't create table (errno: 150) Great, that's fantastic. Here's an example of where this error will occur. CREATE TABLE main(
id INT UNSIGNED NOT NULL AUTO_INCREMENT,
PRIMARY KEY(id)
);
CREATE TABLE other(
id INT UNSIGNED NOT NULL AUTO_INCREMENT,
main_id INT NOT NULL,
PRIMARY KEY(id),
FOREIGN KEY(main_id) REFERENCES main(id)
); So I'm trying to make the table "other" reference the table "main" through the foreign key "main_id" and, if you try it, it'll throw an Error 150. Want the solution? The foreign key "main_id" has to have the exact same type as the primary key that it references. In the example, "main_id" in the table "other" has the type INT NOT NULL while "id" in the table "main" has the type "INT UNSIGNED NOT NULL" and also AUTO_INCREMENT, but that isn't something we have to worry about. To make things incredibly clear, here's the working example. CREATE TABLE main( id INT UNSIGNED NOT NULL AUTO_INCREMENT, PRIMARY KEY(id) ); CREATE TABLE other( id INT UNSIGNED NOT NULL AUTO_INCREMENT, main_id INT UNSIGNED NOT NULL, PRIMARY KEY(id), FOREIGN KEY(main_id) REFERENCES main(id) ); To solve ‘MySQL ERROR 1005: Can't create table (errno: 150)‘ you likely just have to ensure that your foreign key has the exact same type as th
